MC275
Vacuum Tube
Power Amplifier
FULL POWER DELIVERY
The MC275 Series IV delivers
75 watts per channel into
4, 8, and 16 Ohm speakers.
ULTRA LOW NOISE
AND DISTORTION
Distortion-canceling properties
of McIntoshs Unity-Coupled
circuit and unique Output
Transformer design yield
much lower distortion and
noise across the entire
20-20,000Hz music range.
WIDE BANDWIDTH
McIntoshs exclusive
Output Circuit and Transformer
designs ensure ultra-wide
frequency bandwidth.
MONOBLOCK
The two 75-watt channels
may be combined into a single
channel of 150 watts into
2, 4 or 8-Ohm loads.
INVERTED CHASSIS
Heat producing tubes
are located on top of the
chassis, under a protective
cage, while other circuits are
shielded within the polished
Stainless Steel Chassis.
POWER OUTPUT STEREOMinimum sine wave continuous
average power output per channel,
both channels operating is: 75 watts
into 4, 8 or 16 ohm load.
